Hi JP-

I gave it a spin and definitely like it!  I have been using custom
footprints for capacitive sensors, but this is much better.  A couple
thoughts:

1) I'd prefer to have the angle saved as a parameter in the file rather
than a fixed list of options.
2) We'll definitely need to address the polygon issue.  I created a
10cmx10cm board and filled it with 45° at the minimum width/50% fill and my
computer froze for 2 minutes while it thought about it.  Strangely, when I
checked it was only using one core, so I'm not sure why the wm froze during
the calculation.  Maybe some interaction with the graphics card.

If we can't fix the polygons before this, we should probably have a
dummy-check pop-up warning of long compute times.  The polygons get
calculated twice on closing the zone edit window.  Once with the cursor
showing busy and then again with no indication of work.  This happens again
when highlighting.

Best-
Seth
